The Continental Divide here is part of the Northern Divide, and is essentially a drainage divide. Streams in the west, southwest, and south-central parts of North Dakota, such as the James, Cannonball, Cedar, Heart, Knife, and Little Missouri rivers, flow to the Missouri River, which in turn joins the Mississippi River and eventually flows to the Gulf of Mexico. In contrast, streams of the northwest, north, and eastern parts of the state, such as the Souris River, the Red River of the North, and all their tributaries, including the Sheyenne, Goose, Maple, Pembina, Tongue, and Turtle rivers, flow to Hudson Bay. In the southern part of the state, the continental divide runs between the James and the Sheyenne valleys from the border with South Dakota northward toward Harvey. South of Harvey, the divide angles westward and roughly follows a crest in the Missouri Coteau that is slightly west and south of the Missouri Escarpment.
